Everything was working fine until I was prompted to update my Edge 810 to 2.90 from 2.80. I was also prompted to download Garmin Express.
From this point, whenever I create a new course and do 'send to device' I have a positive response saying the course has been successfully loaded to the device but when I check my 810 it states that 'no courses have been saved'
I have tried this on IE11 and Chrome and on a different laptop but get the same result.
I have tried factory reset and reload of 2.90 using webupdater.
I did a ride today and was able to upload my ride to garmin connect ok but still not able to create a course and transfer to my device.
